It's a relay. If you know how relays work, then you should understand that. If not, basically what it does is allow current flow to/from that rear battery only when the car is on (when the isolator senses voltage from the turn-on lead, wherever that may be from depending on how it's wired), and shuts off that path to the rear battery when your car is off. It's beneficial if you play your stereo with your car off, so that if the battery powering your amps dies, you still have your front battery fully charged to start your car, which will then recharge your rear battery. Make sense?
